Abstract (en)
[origin: US2019085835A1] Start-stop engine systems for a turbocharged engine have a bypass with fluid flow from upstream of the compressor or downstream of the compressor to a position between the throttle and the engine, or from between the compressor and throttle to a position upstream of the compressor with a Venturi device in the bypass. A device requiring vacuum is in fluid communication with a suction port of the Venturi device. An electronic vacuum pump is added that is in fluid communication with the device requiring vacuum or with the Venturi device. The electronic vacuum pump is operated during a stop condition of the start-stop engine to replace the vacuum generated by the Venturi device or to provide a pressure drop across the Venturi device so the Venturi device continues to generate vacuum for the device requiring vacuum.
